A new study found that not all geoengineering ideas are created equal。 Brightening marine clouds over the eastern Pacific could dramatically weaken the El Niño cycle, triggering major changes to global weather patterns, while stratospheric aerosol injection left the system largely unchanged。 Researchers say the results are a reminder that efforts t

The unconscious brain appears to be far more capable than scientists once believed。 Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories。 Even more remarkably, neural activity showed signs of predicting upcoming words be

Amid widespread “techlash” over addictive screens and apps, the Yoto, an audio player for children, shows there’s still a way to make money while doing something nice

A decades-old puzzle about water has finally been unraveled。 Researchers found that water trapped in tiny nanoscale spaces is not inherently more reactive。 Instead, the intense pressures created inside these microscopic gaps explain most of the effect, while the surrounding material can further enhance water's chemistry if it interacts with the rea

A pioneering climate scientist is challenging a U。 government report that cited his research while reaching what he says is the exact opposite conclusion。 Benjamin Santer and his colleagues say decades of satellite data clearly reveal the atmospheric “fingerprint” of human-caused climate change

NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways。 The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently。 In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect。 High-fructose corn syrup triggered a stronger response and was preferred by the animals

A surprisingly simple fuel modification could help tackle one of diesel engines’ biggest problems: pollution。 Researchers reviewing studies from around the world found that mixing small amounts of water into diesel fuel can dramatically reduce harmful emissions, including nitrogen oxides and soot, while maintaining or even improving engine efficien

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply。 A new review examined five randomized clinical trials involving 238 participants and found mixed results。 Two studies, both involving women with major depressive disorder, re
